Background/Discussion:

The Pecos Surface Water Treatment Plant (PSWTP), located at 1475 East Pecos Road, was put into service in 1989. The current capacity of the PSWTP is 60 million gallons per day (MGD). The water distribution system includes over 1,200 miles of water mains, 19 reservoir and booster sites, and 30 active drinking water wells, and also receives water from the Santan Vista Water Treatment Plant in Gilbert (owned jointly by the City of Chandler and the Town of Gilbert). The Water Systems Upgrade Program is intended to leverage outside consultants as extensions of staff to expedite the short and long term planning for improvements at PSWTP. On October 19, 2023, City Council approved Agreement No. PW3-925-4631, with Hazen and Sawyer, P.C., for the Water System Upgrade Program consultant services. Through the work to date, key opportunities have been identified to enhance the maximum process and hydraulic throughput of the PSWTP. Amendment No. 1 includes high-rate filtration testing, process testing, and near-term control system programming. Hazen and Sawyer will provide on-site support to city operations personnel, as well as perform data analysis and report on the results of the testing. An additional 120 calendar days has been added for a revised total of 360 days to final completion, following Notice to Proceed.

Evaluation:

On October 19, 2023, City Council approved an agreement with Hazen and Sawyer, P.C., for the Water System Upgrades Program consultant services, in an amount not to exceed $695,720. Amendment No. 1 adds additional services, extends the term of the agreement, and increases the amount of the agreement by $149,680.
